薄層式綠屋頂於不同土層含水量熱收支行為模擬與實驗驗證
Extensive Green Roof Heat Budget Simulation and Experimental Validation in the Case of Different Soil Moisture Contents
摘要
由於全球暖化造成的氣候變遷，極端氣候趨勢愈來愈為顯著，未來的夏天都將面臨更加炎熱的氣候與高用量的夏日空調耗能，為了減少龐大的空調耗能，愈來愈多的建築多採用綠建築策略來減緩氣候變遷造成的影響。 綠建築策略中採各種綠化建築外殼除可阻隔熱流的傳遞、增加外殼的熱質外，植物也可以削減進入建築外殼之太陽輻射，且減少建築物壁面之受熱量進而降低室內溫度，除此之外亦藉由植物生理作用伴隨的熱能釋放幫助建築物散熱，其中以蒸散作用最為顯著，為量化植栽蒸散作用散熱效果，本研究根據文獻之模型與公式撰寫程式模擬植栽土層熱收支行為後進行比較、驗證，以供後續室內溫度或空調耗能模擬。 本研究參考國內外文獻有關研究模擬土壤水分變動趨勢和植栽蒸散模擬，且探討其彼此相依關係，進而透過澆灌量來控制植栽蒸散效果，再由能量平衡去分析整個植栽土壤熱收支行為，最後研究其土壤熱通量之影響，進而利用商業有限元素軟體Abaqus分析其直接對室內溫度造成之除熱效果

Because of the effect of global warming, the electricity consumption in summer has been increasing rapidly. Therefore, this research mainly discusses the different building greening systems in the application to eliminate the thermal effect in building structures. Constructing greening system on a building envelope can effectively retard the heat transfer process through the envelope and at the same time increase its thermal mass. Besides, the physiological effects of plants enhance the ability of heat release, which can help cooling the building. Especially, the heat dissipation of evapotranspiration process is the most significant. In order to quantify the effect of evapotranspiration process, the theory and algorithms according to references have been written in MATLAB language then verified by experiments. So that the model can be utilized to simulate indoor temperature or energy consumption. We study the reference literature related to the soil moisture evapotranspiration simulation about changing trend and effects, and to explore its relationship with each other dependencies. Through the water control the amount of evapotranspiration planting effect, and then to analyze the energy balance of the whole planting soil heat balance behavior.Finally, we study the effect of soil heat flux, and use the software finite element analysis Abaqus of thermal effects in addition to its direct cause of the indoor temperature.
